- obtaining code operable to obtain from a data source master malware definition data, said master malware definition identifying a plurality of items of malware each belonging to one of a plurality of classes of malware threat;
identifying code operable to identify one or more classes of malware threat against which said mobile computing device is to be protected; and
generating code operable to generate from said master malware definition data said mobile computing device malware definition data, said mobile computing device malware definition data identifying items of malware identified within said master malware definition data which are within classes of malware threat against which said mobile computing device is to be protected;
wherein said obtaining code, said identifying code and said generating code are executed by a fixed location computing device, said fixed location computer being operable to transfer to said mobile computing device one or more computer files including at least, a computer file containing said mobile computer device malware definition data;
wherein said fixed location computing device stores profile data identifying one or more different types of mobile computing device to which said fixed location computing device transfers computer files and corresponding threat data identifying one or more classes of malware threat to which each of said mobile computing devices is vulnerable;
wherein only a subset of said master malware definition data is used to generate said mobile computing device malware definition data for tailoring said mobile computing device malware definition data to accommodate malware threats to which said mobile computing device is vulnerable;
wherein said one or more classes of malware threat against which said mobile computing device is to be protected are chosen according to classes of malware threat known to pose a problem to said mobile computing device, and classes for which it is desired to protect said mobile computing device according to user defined policies;
wherein fixed location computing device also transfers a malware scanner computer program from said data source to said mobile computing device; and
wherein said fixed location computing device checks for an undated malware scanner computer program becoming available from said data source and, if such an undated malware scanner computer program become available, then obtains said undated malware scanner computer program for transfer to said mobile computing device.

Abstract
Malware definition data for mobile computing devices 2 is generated from master malware definition data 44 by selecting those classes of malware threat to which the mobile computing device is vulnerable and then selecting the matching malware items from within the master malware definition data. A PC 6 to which the mobile computing device may be connected is responsible for downloading an updated version of the master malware definition data for its own use and generates appropriate mobile computing device malware definition data for transfer to the mobile computing device when it is connected to the PC. The scanner programs of both the PC and the mobile computing device may be similarly updated.
